One piece folding razor



June 18, 1935. A w. KRIEGER ONE-PIECE FOLDING RAZOR Filed March 6, 1954 Ada/f WW2? aw Patented June 18, 1935 UNITED STATES PATENT OFFICE 7 Claims.

The purpose of the invention is to provide a folding safety razor of the one-piece type in which the guard is hinged to the comb and in which the handle, which holds the guard, may be folded.

The invention is a safety razor which is formed in one piece with the back or guard hinged to the comb and the handle rotatably mounted in the comb thru a hinged joint so that it may fold against the comb. The guard hinge also holds one end of the blade, and a reservoir is provided in the handle.

Many types of safety razors have been provided and a few are formed in one piece with the parts thereof hingedly connected, with the exception of the blade, however, in these few it is necessary to turn the handle so that it has been necessary to pivotally mount the handle in the comb and in order to do this, it is necessary that the handle remain perpendicular thereto, or in such a position that it will stand outward, so that it requires a box or container that is much larger than would be required if the handle were to fold against the comb.

The object of the invention is, therefore, to provide means for permanently mounting the handle of a safety razor in the comb so that it may readily be folded against the comb of the razor.

Another object is toprovide means for rotatably mounting the handle of a safety razor in the razor so that the handle may be used for clamping the blade and also so that it may be folded.

A further object is to provide a safety razor having a rotatable handle pivotally mounted therein.

A still further object is to provide means for clamping a safety razor guard against the comb by the handle in which the handle may readily be folded.

And a still further object is to provide a onepiece safety razor having a folding handle, which is of a simple and economical construction.

With these ends in view the invention embodies a safety razor having a comb,'a guard hinged to one end of the comb, and adapted to hold razor blades against the comb, a handle rotatably mounted in the comb and adapted to clamp the guard against the comb, means hinging the handle in the comb, and a cap at the outer end of the handle forming a closure for a compartment therein. T

Other features and advantages of the invention will appear from the following description taken 'inconnection with the drawing, wherein:

Figure 1 is a view showing the side elevation of the razor in the closed position.

Figure 2 is an end view of the razor shown in Figure 1.

Figure 3 is a view similar to that shown in Figure 1 with theguard open.

Figure 4 is a detail showing a caustic stick that may be inserted in the handle of the razor.

Figure 5 is also a detail showing a pair of tweezers that may be incorporated in the handle of the razor instead of the caustic stick.

Figure 6 is a longitudinal section thru the razor showing the method of mounting the parts thereof.

Figure 'Yis a cross section thru the razor with one of the handle holding elements shown in full.

Figure 8 is a detail showing an assembly of the handle holding elements with. one of the elements shown in section.

Figure 9 is a plan View of the razor with the guard raised and shown in. sections, showing a razor blade on the comb with the end of the blade held between the hinges so that the hinges compensate for lugs normally provided at the ends of the comb for locating the blade.

In the drawing the razor is shown as it may be made wherein numeral l indicates the base which is commonly called the comb, numeral 2 indicates the back which may be termed the guard, and numeral 3 indicates the handle which may be solid or hollow, as may be desired.

' The comb l is made as shown in Figures 6 and 7 with a comparatively solid central portion having the comb teeth 4 extending from the edges, projections 5 extending from the upper surface and positioned to correspond with openings in a razor blade so that they may locate and hold the blade upon the comb, and in the center of the comb is a slot 6 thru which the end of the handle may extend so that it may be screwed into the guard 2, as shown in Figure 6. On the sides of the slot 6 are ears I and 8 in which bearings 9 and it are rotatably mounted and pins ll and i2 extend between the bearings, as shown in Figure 8. The inner end of the handle 3 is' formed with a continuous circular recess l3 that is held between the pins H and I2 so that the handle may rotate to screw the inner end thereof into the guard 2, and may also be turned to the position indicated by the dotted lines I4, shown in Figure 6, when it is desired to fold or pack the razor. The handle is formed with bosses l5 and. 16 on the sides of the recess I3 and aninner end I! extends upward from the boss l5, and the end thereof is provided with threads !8 by which it may be screwed into a threaded opening l9 in the guard 2, and it will be seen that by turning the handle 3 the guard 2 may be drawn down against a razor blade that may be held between the guard and comb, so that the blade may be rigidly clamped and held while it is used. It will be understood that whereas the handle is shown provided with a continuous groove I3 held between the pins l l and l 2, it may also be rotatably held between the members I and 8 in any other manner, or by any other means. From the boss J6 the handle tapers slightly outward and a gripping surface of any design may be provided on the outside thereof so that it may readily be gripped and held by hand. The handle 3'may' be hollow, as indicated by the dotted lines 20 in Figure 3, and a bushing; 2| may be threaded into" the handle, as shown at the point 2 2, inwhich the threaded part 23 of the bushing 2| is screwed into threads on the interior of the handle. The bushing 2 I may be used as a closure for the end of the handle, so that any object or device may be stored in the handle, however, it will be understood that the bushing may also be made integral withthe handle so that it will form a direct part thereof. Any object or device may be mounted in the bushing and arranged so that it will extend into the handle and, in Figure 4,

the bushing is shown with a caustic stick 24 mounted therein, whereas in Figure it is shown with tweezers 25 mounted therein. These devices may be mounted in the bushing in any manner, and any other devices may also be mounted therein, or used in combination therewith.

-The guard 2 is formed of a substantially flat piece of material with the under and outer surfaces curved, as shown in Figure '7, and with projections 26 extending downward from one end which extend into slots 21 in the comb, and are hingedly held by pins 28 in slotted holes so that the guard may be raised, with the handle unscrewed therefrom, to the position shown in Figure 3, and in this position a razor blade may be placed on or removed from the comb I. The razor blade may be placed upon the comb with an opening in the center fitting over the end I! of the handle and openings adjacent the ends fitting over the projections 5. It will be understood, however, that razor blades of any type may be used and the openings therein may be arranged in any manner, and it will also be understood that any means may be provided on the comb for locating and holding the blades.

The under surface of the guard 2 is provided with recesses 29 corresponding with the projections 5, and these projections will extend upward into the recesses, as shown in Figure 6.

It will be understood that other changes may be made without departing from the spirit of the invention. One of which changes may be in the use of other means for hinging the guard 2 to the comb I, another may be in the use of other means for movably attaching the handle to the comb, or other part of the razor, another may be in the use of other means for holding the guard, and still another may be in the use of a, handle of this type in combination with a razor of any other type.

The construction will be readily understood from the foregoing description. In use the razor maybe provided as shown and described and'it Will be noted that normally it will be packed with the handle in the folded positior'nas indicated by the dotted lines in Figure 6, and when it is desired to use the razor the guard 2 may be raised, the handle moved to a position perpendicular to the comb, a razor blade placed upon the comb, the guard 2 lowered, and by turning the handle, the inner end thereof will screw into the guard and thereby clamp the guard against the comb withthe razor blade held between the guard and comb. It will therefore be noted that screwing the end of the handle into the guard not only holds the blade, but also positively holds the handle in the position in which it may be used and the particular mounting for the'handle makes it possible to turn the handle to screw it into the guard and also to fold the handle against the comb and guard. This provides a safety razor of the one-piece type in which all of the parts are attached or hinged so that they will remain intact when not in use.

1 With the razor formed in this manner any type of blade may be used and the blade'may be made as shown in Figure 9 or may be formed with a continuous slot or with a curved slot,- or with three openings, or with any number of openings, and with openings of any shape, so that razor blades of any make may be used and, as practically all blades are now made with notches in the corners by which they may be located, the ends between the notches will fit between the hinge, as shown in'Figure 9, sothat this end of the blade may readily be held in place. Lugs may also be provided at the opposite end similar to those of many types of safety razors. Any other means may be used for holding or locating the blades, and these may be provided for a special blade, or for any blade now in use.

It will also be understood that, whereas a caustic stick and a pair of tweezers have been shown as adapted to be placed in the handle, in-

struments or objects of any type or description may be used in the handle in combination therewith. The opening in the handle may also be of any shape or design and arranged to accommodate objects of any type.

Having thus fully described the invention, what I claim as new and desire to secure by Letters .Patent, is:

l. A safety razor of the I one-piece type in which one end of the guard is hinged to one end of the comb, having a handle, said handle being adapted to hold securely together said guard and comb pieces with the blade between them, said comb having projections from the lower side thereof, said projections having bushings there.- in, said bushings being adapted to turn therein and having pins adapted to co-operate with a groove in the shank of said handle, said pins and groove forming a semi-universal joint allowing the handle to be rotated about'its axis and also in a plane perpendicular to the comb, said comb having a slot adapted to permit said handle to rotate in a plane perpendicular to said; comb when said handle is released from the guard plate.

2. A safety razor of the one-piece type having a guard, a comb and a handle, in which the razor blade is held between the guard and 'comb' by the handle, said comb having bushings rotatably mounted therein and pins extending between said bushings, and said handle having a continuous circular recess held between said pins:
